Zero GravityInspired by NASA technology, the Zero gravity position is the perfect position to enjoy a massage, aligning your back relative to your thigh at an optimal level of comfort. When reclined into the zero gravity position, the complete weight of your back is virtually supported by the backrest which maximizes the intensity of the massage. This also reduces the vertical stress on the spine. There are 2 stages of zero gravity, the 2nd being more reclined. Study show that when the legs are at or above heart level, it promotes better circulation. |
Auto Body ScanEquipped with the latest technology, It allows for the rollers to map the back curvature with even more accuracy, which translates into a more precise massage hitting all the key areas. |
True Ergonomic S-TrackThe OS-4000 Zero Gravity massage chair is ergonomically designed to contour a variety of spine shapes. The Spine curvature is unique from one individual to the next. The S-track system allows the roller heads to massage along the back from the neck down to the lower spine with a consistent pressure in the massage, along with a comfortable support. The typical massage tracks, being linear, create an inconsistency in pressure applying weak massages in the neck and lower back. |
Full Body Air MassagesThrough innovative engineering, we have reduced the total number of air bags but have increased the volume and surface area of massage. By doing so the total number of working valves has drastically reduced from prior model. Which ultimately puts less stress on the chair, making it one of the most mechanically sound massage chairs in the market. |
